Kavli Affiliate: Tom Abel | First 5 Authors: Yunchong Wang, Arka Banerjee, Tom Abel, ., | Summary: Distances to the $k$-nearest-neighbor ($k$NN) data points from volume-filling query points are a sensitive probe of spatial clustering. Here we present the first application of $k$NN summary statistics to observational clustering measurement, using the 1000 richest redMaPPer clusters […]
